Of Georgia's 2013 opponents, LSU is losing six, Tennessee is losing three, South Carolina, Missouri, and Auburn are all losing one. Florida is losing three. LSU is losing some pretty strong players, particularly Ware and Ried. Two of Florida's three are important parts of the Gators' defense this year.

But are there any three bigger players for a team than Tyler Bray, Cordarrelle Patterson and Justin Hunter?
Patterson and Hunter accounted for over 1850 of the Vols' 3787 yards of receiving this past year. When you consider they are also losing TE Mychal River and WR Zach Rogers to graduation, that is over 2/3 of their receiving yards and 185 of their 285 receptions.

As an aside, by my count, 20 of the 40 who have already declared are current or former SEC players (Da'Rick Rogers has declared), with Alabama yet to play. The date for Juniors to declare is January 15th.
